ADAS stands for Advanced driver-assistance systems. ADAS are all those sensors alerting you to not hit a surrounding object or the fancy gizmos that you bought with your car that help to avoid accidents. This includes blind-spot monitors, lane-keep assists, pre-collision braking, and a whole lot more depending on the year and makes of vehicle.
Not that long ago, the only safety item in your car that required any type of recalibration after a collision was the airbags. Nowadays, those airbags are in the front the sides and all over to protect you and your passengers. In older cars it was easy to find what was wrong because the airbag light would light up on the dash telling body shops that it needed to be reset, or the collision caused a problem like a loose wire somewhere in the system.
Well, today, there are no easy to spot lights for faulty ADAS systems due to the growing complexity. This is why scanning for affected safety systems is so important after a collision and whats worse, you will have no way of knowing if they are throwing off fault codes unless your body shop does.
And if you think that your body shop is automatically doing all this for you, consider this, vehicle diagnostics provider CarMD reported that its third-party PRO SCAN tool had found issues on 80 percent of 5,642 vehicles checked by repairers.
CarMD wrote that “a majority” of those 80 percent had “hidden problems not likely identified by a visual vehicle inspection alone.”
“On average, these vehicles had six issues that needed to be checked, repaired, or replaced, resulting in improved peace of mind for vehicle owners and increased average repair order (ARO) for shops,” the company continued in a news release.
In summary, what CarMD found is that of the body shops that use their scanning tools, 80% of the vehicles scanned had other system issues that were otherwise undetectable because the do not have an indicator light on our car’s dashboard. We think that’s pretty alarming.
Of all the cars scanned, only 32 percent of them displayed the more common check engine light, which is not collision or ADAS related.
But on the 68 percent without a check engine light, “nearly three quarters (74%) of these vehicles … reported a problem with one or more system. On average, each vehicle had six different modules that required attention, resulting in additional work for the shop.”
“The most common Network System codes were related to the Body Control Module (BCM), Transmission Control Module (TCM), Instrument Panel Cluster (IPC), Powertrain Control Module (PCM), Engine Control Module (ECM) and radio.”
Here is the part that impacts customer safety, though: “Some less commonly diagnosed issues, but equally important due to their potential impact on passenger safety, were a faulty backup camera, adaptive cruise control, adaptive headlights, lane departure alert and seat belt retractor motor module.”
CarMD spokeswoman Kristin Brocoff confirmed these 74 percent didn’t throw any of the other dash lights either.
“In most of those cases it was an issue that doesn’t report a dashboard warning light at all,” she wrote in an email. “Other scenarios included situations where a CEL bulb was removed or disconnected from the combination meter. In others, it was an intermittent issue that hadn’t triggered a warning light.”
Hopefully now you can see, it is important that you do your research and find a body shop that is going to cover every aspect of your collision repair, including a pre and post-repair scan and calibration, but you may be wondering why might a shop would elect not to scan the vehicle?
Believe it or not, there are still plenty of body shops that exist who choose to still fix cars the same way they did decades ago simply because “it has always worked”. What is more alarming is some of these shops choose to completely ignore the proper steps or don’t even know that they need to perform them in order to restore you car back to full functionality with its safety features.
Here at Statesville Collision Center, we recognize that any vehicle that has not been pre and post-repair scanned is a liability to the customer and to our business. So we choose scan every car that is in our shop and that should reassure you that you are receiving the most safe repair.
